In another embodiment, FIG. 7 illustrates an example in which a punchingpart 11 is disposed in the connection device 1, and when anaccommodation part 500 filled with a different kind of material(hereinafter, referred to as a “different material”) is assembled withthe connection device 1, an opening unit 501 of the accommodation part500 may be opened by the punching part 11 to allow different materialfilled in the accommodation part 500 to be dropped and mixed. Thus, thepunching part 11 may have various structures, and for example, thepunching part 11 may push and open a lower portion of the accommodationpart 500 or tear a portion of a surface of the accommodation part 500.

As further another embodiment of the present invention (see FIG. 8), thepresent invention may be designed so that the connection device 1 of thepresent invention is capable of being coupled to containers havingvarious standards. According to the features, a screw thread part S hasa predetermined angle and a thin thickness.

Also, in use, FIG. 8 illustrates an initial state that is assembled withthe container neck 200. In this state, when the connection device 1further rotates, the connection device 1 contacts the screw thread 201and is flexibly expanded outward according to a size of the screw thread201 and thus be coupled to the screw thread 201. Here, to improve theflexibility, other rubber material such as silicon may bedouble-injected to a predetermined portion.

As further another embodiment of the present invention (see FIG. 9), thecurrent embodiment is similar to that of FIG. 8. However, according tofeatures of the current embodiment, the screw thread part S has apredetermined thickness, and a portion of a screw thread part S is cutto improve elasticity (flexibility) of the screw thread part S. Then,the cut portion is treated as a flexible part 12. Here, this may bemolded by using the multi-injection molding machine.

The flexible part 12 may be formed of a soft synthetic rubber materialsuch as silicon.

According to further another embodiment of the present invention (seeFIGS. 10 and 11), to apply the connection device to container neckshaving standards different from each other by using a single screwthread part S, the screw thread part S has to have flexibility(elasticity). For example, when the screw thread part S is disposed onthe screw thread 201 of the container neck 200, the screw thread part Smay spread outward along an outer diameter of the screw area 201 by aspace 13 or be pushed inward, and thus is closely-attached to the screwthread 201.

For supplemental explain, FIGS. 10 and 11 illustrate an initial state inwhich the connection device 1 is assembled with the container neck 200.In this state, when the connection device 1 rotates toward the containerneck 200, in the case of FIG. 10, an upper portion of the screw threadpart S spreads outward with respect to a lower portion thereof ordisposed inside the lower portion. Also, in the case of FIG. 11, thelower portion of the screw thread part S is flexible inward or outwardwith respect to the upper portion thereof. This may depend on a positionof a cut space 13. That is, the cut space 13 may be set at variousangles in vertical or horizontal directions.

As further another embodiment of the present invention (see FIG. 12),upper and lower portions of the screw thread part S spreads outward withrespect to a portion where the screw thread exists. Furthermore, toimprove elasticity, a soft resin such as silicon may be added to atleast one of the upper and lower portions to form a flexible part 12.The flexible part 12 may be preferably molded by using a multi-injectionmolding machine. (FIG. 12 illustrates a process of initially assemblingthe connection device 1 with the container neck 200)

As further another embodiment of the present invention (see FIG. 13),FIG. 13 illustrates an example of a process of initially assembling withthe container neck 200. According to feature of the current embodiment,a foldable screw thread part S is provided inside the connection device1. The foldable screw thread part S is inclined downward when injectionmolding is performed, and then, is maintained upward at a predeterminedangle through a past-process. Thus, the foldable screw thread part S haselasticity.

Thus, the screw thread part S is assembled with the screw thread 201along the screw thread 201 in a state where the screw thread part Sspreads outward according to the size of the screw thread 201 of thecontainer neck 200 or while maintaining inward elasticity. The foldablescrew thread part S may have a circular shape or be a plurality ofindependent screw threads S of which a predetermined portion is cut.Also, when the screw thread part S has a circular shape, the screwthread part S may have a predetermined slope (angle) to correspond tothe screw thread 201.

As further another embodiment of the present invention (see FIGS. 14 and15), the screw thread part S is separately formed of a material havingexcellent elasticity to maximize the elasticity thereof, and the screwthread part S is assembled with the inside or the outside of theconnection device 1. FIGS. 14 and 15 illustrate an initial state inwhich the connection device 1 is assembled with the container neck 200.

As further another embodiment of the present invention (see FIGS. 16 and17), the screw thread part S faces an upper side with respect to thelower side thereof. To realize the screw thread part S having apredetermined angle, an upper-opened space 13 is provided inconsideration of manufacture of a mold. Also, at least two screw threadparts S may be operably provided on the container neck 200

Also, FIG. 16 illustrates an initial state in which the connectiondevice is assembled with the container neck, and FIG. 17 illustrate astate in which the connection device is assembled with the containerneck. That is, the screw thread part is in a state in which an end ofthe screw thread part is lifted from the outside of the screw threadpart toward an upper end inside of the screw thread part.

As further another embodiment of the present invention (FIG. 18), whenan auxiliary support 120 is screw-coupled to the outside of theconnection device 1 in a rotation direction, the screw thread part S isclamped inward so that any container neck or the other container neckhaving a similar standard may be applied to the screw thread. In somecases, a predetermined portion of the screw thread part S may bemaintained in a cut shape.

As further another embodiment of the present invention (see FIG. 19),FIG. illustrates a storage space 132 filled with the different materialmay be defined in the connection device 1 having the various screwthread parts S (FIG. 19 is an initial state in which the connectiondevice is intended to be coupled to the container neck).

In use as described above, when a cover disposed on the outside or anelastic part 130 formed of a soft resin such as silicon or the like isremoved, and an end on which a stopper 131 is disposed is pressed, theelastic part 130 is folded downward. Simultaneously, a breakingprotrusion disposed under the stopper 131 to lengthily extend may breaka sealing part, which has a thin film shape to seal a lower end of thestorage space 132, so that the different material within the storagespace 132 drops down and is mixed.

According to further another embodiment of the present invention (seeFIG. 20), a screw thread part S of the present invention includes afirst screw thread 5 having a thin thickness to provide elasticity. Asecond screw thread 6 disposed under the first screw thread 5 isfoldable. Thus, when the first screw thread 5 operates and then iscoupled to the container neck 200, the second screw thread 6 may providethe elasticity so that the connection device 1 moves downward withoutbeing disrupted with respect to a skirt of a bottle lid remaining on thecontainer neck 200. Here, the second screw thread 6 may be manufacturedin a partially cut shape.

For reference, the screw thread part 4 may be called a coupling part,and the present invention may have the same means.
